Description

[Technical field]

[0001] The present invention relates to a composition, preferably a cosmetic composition, more preferably a dermocosmetic composition. [Background technology]

[0002] Oil-in-water (O / W) emulsions and water-in-oil (W / O) emulsions are well known in the fields of cosmetics and dermatology, in particular for the preparation of cosmetic preparations such as milks, creams, tonics, serums and lotions. In particular fine emulsions, such as O / W nano- or microemulsions, are of particular interest due to their transparent or slightly translucent appearance.

[0003] Typically, fine emulsions can be formed by using surfactants. For example, WO2014 / 98265 discloses nano- or microemulsions formed using a combination of several surfactants.

[0004] However, fine emulsions are sometimes unstable over time, especially under temperature changes, e.g. from high to low temperatures and vice versa, so that they undergo phase separation and do not exhibit a transparent or slightly translucent appearance.

[0020] After extensive investigation, the inventors have discovered that by using a combination of selected oils and diols, it is possible to provide a composition that is stable over time and can exhibit a transparent or slightly translucent appearance.

[0021] Therefore, the present invention provides (a) at least one oil; (b) at least one diol having at least one carbon chain having a total number of carbon atoms of 5 or 6, including 3 or more carbon atoms; (c) Water and A composition comprising: (a) the oil is selected from the group consisting of (i) fatty alcohols, (ii) fatty acids, (iii) monocarboxylic acid monoesters, (iv) dicarboxylic acid diesters, (v) N-acyl amino acid esters, and (vi) alkyl lactates; - (i) the fatty alcohol and (ii) the fatty acid each contain a branched alkyl group or a linear or branched alkenyl group having from 4 to 30, preferably from 5 to 26, more preferably from 6 to 22 carbon atoms, (iii) the monovalent carboxylic acid monoester comprises a branched alkyl group or a linear or branched alkenyl group, each having 4 to 30, preferably 5 to 26, more preferably 6 to 22 carbon atoms, (iv) the divalent carboxylic acid diester comprises at least one branched alkyl group having 3 to 10, preferably 3 to 8, more preferably 3 to 6 carbon atoms, and an alkylene group having 6 to 18, preferably 6 to 14, more preferably 6 to 10 carbon atoms; - (v) the N-acylamino acid ester comprises a branched alkyl group having 3 to 10, preferably 3 to 8, more preferably 3 to 6 carbon atoms, and a linear or branched acyl group having 4 to 30, preferably 5 to 26, more preferably 6 to 22 carbon atoms, - (vi) the alkyl lactate comprises a linear or branched alkyl group or a linear or branched alkenyl group, each having from 4 to 30, preferably from 5 to 26, more preferably from 6 to 22 carbon atoms, and (b) the mass ratio of the amount of the diol having at least one carbon chain containing 3 or more carbon atoms and having a total number of 5 or 6 carbon atoms to the amount of the (a) oil is 4 or more, preferably 5 or more, more preferably 6 or more; Concerning the composition.

[0022] The compositions according to the present invention are stable over time and can exhibit a clear or slightly translucent appearance.

[0023] The compositions according to the invention are stable over time even under temperature changes, for example from a higher temperature to a lower temperature or vice versa, so that they do not undergo any phase separation while maintaining a homogeneous appearance.

[0024] The composition according to the present invention comprises at least one oil and is therefore capable of enhancing the radiance of the skin when applied onto the skin.

[0025] The composition according to the present invention can contain a relatively large amount of oil, and therefore can provide better cosmetic effects, such as enhanced skin radiance, that are brought about by a relatively large amount of oil.

[0026] The composition according to the present invention can also impart a fresh texture when used, so the composition according to the present invention can impart a non-greasy texture.

[0027] Compositions according to the invention can be clear or slightly translucent, but are preferably clear.

[0028] The composition according to the present invention does not need to contain any surfactant. Therefore, the amount of surfactant in the composition can be limited to 1% by mass or less, preferably 0.1% by mass or less, more preferably 0.01% by mass or less, based on the total mass of the composition. It is most preferable that the composition according to the present invention does not contain any surfactant.

[0029] It has been well known that surfactants can impart a greasy texture and irritation to the skin.

[0030] Therefore, when the composition according to the invention comprises only limited amounts of surfactants, the composition according to the invention can still impart a less greasy texture.

[0031] In addition, when the composition according to the present invention contains only a limited amount of surfactant, the composition according to the present invention may impart less irritation to the skin.
